We recently purchased our FR and live in it full time. The slides are hydrolic and will be out more then in what is a good product to coat the exposed cylinder to prevent rust we are on the Oregon coast , it rains here from time to time not to mention the salt air. Thanks in advance

A hydraulic cyclinder shaft shiny part shouldn't rust at the tip might if not chrome plated right. Being said I have heard others saying that it can. I would try white lithium grease in the can and use disposal glove to coat. Something that would stay awhile and help the wiper seal on the packing.
